1BMSWind Speed NRG05/08/201713:30:0011/16/201712:15:00The 22 and 42 ft anemometers cups have been destroyed by a heavy hail storm at SRRL. Wind speed data at these levels (and wind shear) should not be used. Wind Speed data is forced to a missing value as of 5/12/2017 at 14:19 MST. On 11/16/2017, the anemometers and wind vanes were replaced with calibrated sensors. In addition the 42 ft booms were abandoned and new boom was installed at 33 ft (10 meters).
2BMSWind Speed NRG07/01/201508:48:0005/12/201714:18:00On 6/20/2012 at 8:59 MST the 22 and 42 foot pulse input channels were swapped on the logger (and program updated) when troubleshooting the spiking problem at the 42 ft level. Unfortunately after troubleshooting was complete the channel was not returned to normal. Since the wire was labeled with the original channel, when the logger was upgraded from a CR10X to a CR800 on 7/1/2015 the wire was put in the original channel however the program was not reverted to the original channel, therefore the data for 22 and 42 levels are reversed during this time. As of 12/29/2017, Wind Speed data (and wind shear) was corrected for both the daily and monthly data sets.
3BMSWind Speed NRG09/09/200800:00:0007/01/201500:00:00There has been a rare spiking problem with the highest wind speed sensor (42 foot level), that can create bogus wind gust readings during times of high atmospheric electric field (as measured by SRRL's EFM). Exact start date is unknown, but it assumed that it started after the tower move (required by Sun Edison PV plant). On 6/20/2012 at 8:59 MST the 22 and 42 foot pulse input channels were swapped on the logger (and program updated) to see if its a problem with the logger channel. This problem was resolved when the data logger was upgraded from a CR10X to a CR800 on 7/1/2015.
